184 /* We have some black magic here
185 * PalmOS ROM on recover expects special struct physical address
186 * to be transferred via PSPR. Using this struct PalmOS restores
187 * its state after sleep. As for Linux, we need to setup it the
188 * same way. More than that, PalmOS ROM changes some values in memory.
189 * For now only one location is found, which needs special treatment.
190 * Thanks to Alex Osborne, Andrzej Zaborowski, and lots of other people
191 * for reading backtraces for me :)
